     from the respective oxo compounds. Furthermore, he invention relates to a process for the preparation of triazole compounds from oxiranes II.

The present invention relates to a process for providing oxiranes usingan aqueous solution of trimethylsulfonium methylsulfate in the presenceof a base, and optionally further converting the resulting oxiranes intotriazole compounds by reacting the substituted oxiranes with1H-1,2,4-triazole under basic conditions. Further, the invention relatesto a process for providing certain substituted triazoles. Furthermore,the invention relates to an aqueous reagent of trimethylsulfoniummethylsulfate and its use for the conversion of oxo-groups intooxiranes.

The substituted oxiranes provided by the process according to thepresent invention are valuable intermediate compounds for the synthesisof triazole compounds having pesticidal, in particular fungicidalactivity. Triazole compounds that are accessible via an oxiraneintermediate are, for example described in WO 2013/010862(PCT/EP2012/063526), WO 2013/010894 (PCT/EP2012/063635), WO 2013/010885(PCT/EP2012/063620), WO 2013/024076 (PCT/EP2012/065835), WO 2013/024075(PCT/EP2012/065834), WO 2013/024082 (PCT/EP2012/065850), WO 2013/024077(PCT/EP2012/065836), WO 2013/024081 (PCT/EP2012/065848), WO 2013/024080(PCT/EP2012/065847), WO 2013/024083 (PCT/EP2012/065852) and EP 2559688(EP 11177556.5), that are directed to specific fungicidal substituted2-[2-halogen-4-phenoxy-phenyl]-1-[1,2,4]triazol-1-yl-ethanol compounds.WO 2013/007767 (PCT/EP2012/063626) is directed to fungicidal substituted2-[2-halogenalkyl-4-phenoxy-phenyl]-1-[1,2,4]triazol-1-yl-ethanolcompounds, that can also be synthesized via a respective oxiraneintermediate compound. A common process for the synthesis of oxiranesfrom carbonyl compounds such as aldehydes and ketones is the reactionwith trimethylsulfonium iodide in the presence of a base (JACS 1965, 87,p 1353ff). This reagent is very expensive and not suitable forindustrial scales. An alternative reagent is trimethylsulfoniummethylsulfate that can be obtained from dimethylsulfide anddimethylsulfate (Heterocycles 8, 1977, p. 397 ff). However, this reagent(melting point 100 to 104° C.) is very hygroscopic and difficult tohandle in solid form (Synth. Communications, 15, 1985, p 753). Forexample an exact dosage of said reagent is only possible under theexclusion of atmospheric humidity. In J. Agric. Food Chem. 2009, 57,4854-4860 certain2-arylphenyl-ether-3-(1H-1,2,4-triazol-1-yl)propan-2-ol derivatives aresynthesized via an oxirane.

Synthetic Communications 15, 1985, p. 749ff. generally describes thereaction of trimethylsulfonium methyl sulfate with aldehydes and ketonesusing 50% NaOH solution. However, not with every ketone or aldehyde,satisfying yields can be achieved, in particular, aldehydes that aremore reactive are reacted. According to this document, NaOH is used asbase for the reaction and high amounts of water are used because thebase is added as 50% aqueous solution. Furthermore, high excess of baseand preferably methylenechloride are used in the process, which is notsuitable for an industrial process also because of environmental issues.

A. A. Afonkin et al. In the Russian Journal of Organic Chemistry, vol.44, no. 12, 2008, pp 1776 to 1779, is directed to the synthesis of someelectron-rich aryl (heteroaryl) oxiranes under phase-transfer andhomogenous conditions using trimethylsulfonium methyl sulfate asreagent. In this reference, the reaction of aldehydes is described thatare generally more reactive than ketones. NaOH is used as 50% aqueoussolution, i.e. high amounts of water are present.

DE3733755 is directed to a process for the preparation of2-(4-chlorophenyl-ethyl)-2-tert-butyloxirane from the respective ketoneusing trimethylsulfonium methylfulfate in the presence of potassiumhydroxide, dimethylsulfide and water. According to this document, theamount of water present in the reaction must be between 1.0 and 1.5 moleper mole of ketone, otherwise the yields are not high enough. Suchrestricted amounts of water are, however, not favorable for anindustrial process.

Consequently, the methods known from the literature are sometimes notsuitable for the efficient synthesis of substituted oxiranes because theyield is not sufficient and/or the reaction conditions and parameterssuch as water content and/or the proportion of the reactants andingredients to each other are not suitable for an upscale toindustrially relevant amounts. Inter alia because some oxiranes arevaluable intermediates for the synthesis of triazole compounds withpromising fungicidally activity, there is an ongoing need for improvedprocesses that easily make such intermediates and compounds available.

An object of the present invention was to provide an improved processfor the synthesis of oxiranes that are valuable intermediates for thepreparation of fungicidal active triazole compounds starting from therespective oxo-group containing compounds. Furthermore, the objectunderlying the present invention was to optimize the synthesis oftriazole active compounds using said oxiranes.

It has now surprisingly been found a highly efficient synthesis for theconversion of specific oxo-group containing compounds into oxiranes thatare useful as intermediates in the synthesis of certain pesticidaltriazole compounds.

The reagent IV is preferably used in an amount of 1.1 to 2.5, inparticular 1.2 to 2, more specifically 1.3 to 1.6 equivalents of IV per1 equivalent (mole) of compound III.

In general, the reagent of formula IV can be prepared fromdimethylsulfide and dimethylsulfate. According to one embodiment of theinvention, reagent IV is prepared in-situ by adding dimethylsulfate tothe reaction mixture containing dimethylsulfide. The dimethylsulfide isusually used in excess.

In a first process, for example, phenoles A are reacted, in a firststep, with derivatives B, wherein X¹ stands for I or Br, in particularBr (=bromo derivatives III), preferably in the presence of a base toresult in compounds C.

Thereafter, the resulting compounds C, in particular X¹ is Br, are thentransformed into Grignard reagents by the reaction with transmetallationreagents such as isopropylmagnesium halides and subsequently reactedwith acetyl chloride preferably under anhydrous conditions andpreferably in the presence of a catalyst such as CuCl, CuCl₂, AlCl₃,LiCl and mixtures thereof, to obtain acetophenones D.

In a second process to obtain the precursors is as follows In a firststep, a halo derivative E, wherein X² is halogen, in particular F, andX³ is halogen, in particular Br, is reacted with a transmetallationagent such as e.g. isopropylmagnesium bromide followed by an acylchloride agent R¹COCl (e.g. acetyl chloride) preferably under anhydrousconditions and optionally in the presence of a catalyst such as CuCl,CuCl₂, AlCl₃, LiCl and mixtures thereof, to obtain ketones F.

The crystal form A of compound I.3 according to the invention is easierto handle than the previously known form of compound I.3 (known e.g.from PCT/EP2012/063626), since during production form A is obtained inthe form of discrete crystals or crystallites having increased particlesize in comparison to other forms of compound I.3. Increased particlesize and the compact habit of form A facilitates filtration from motherliquour and allows easer drying of the solid material.

Compared to the known forms of compound I.3, pure form A is likely todisplay increased stability with regard to conversion into anothermodification. The stability of formulations which contain the compoundI.3 in form A is likely higher than the stability of formulations whichcontain mixtures of different modifications of compound I.3. The terms“pure form A” should be understood to mean that the proportion of themodification in question, based on the total quantity of compound I.3,is at least 80% by weight in particular at least 90% by weight andespecially at least 95% by weight. Accordingly, a further object of thepresent invention relates a composition of the compound I.3 which atleast 80% by weight, in particular at least 90% by weight or at least95% by weight consists of the crystalline form A, based on the totalamount of the compound I.3, contained in the composition.

The crystal form A of compound I.5 according to the invention is easierto handle than the previously known forms of compound I.5 (known e.g.from PCT/EP2012/063626), since during production form A is obtained inthe form of discrete crystals or crystallites having increased particlesize in comparison to other forms of compound I.5. Increased particlesize and the compact habit of form A facilitates filtration from motherliquour and allows easer drying of the solid material.

Compared to the known forms of compound I.5, pure form A is likely todisplay increased stability with regard to conversion into anothermodification. The stability of formulations which contain the compoundI.5 in form A is likely higher than the stability of formulations whichcontain mixtures of different modifications of compound I.3. The terms“pure form A” should be understood to mean that the proportion of themodification in question, based on the total quantity of compound I.5,is at least 80% by weight in particular at least 90% by weight andespecially at least 95% by weight. Accordingly, a further object of thepresent invention relates a composition of the compound I.3 which atleast 80% by weight, in particular at least 90% by weight or at least95% by weight consists of the crystalline form A, based on the totalamount of the compound I.5, contained in the composition.

ANALYTICS

The X-ray powder diffractogramm of forms A and B were recorded with aPanalytical X'Pert Pro diffractometer in reflection geometry in therange from 2θ=3°-35° with a step width of 0.0167° using Cu-Kα radiation(1.54178 Å) at 25° C. The recorded 2θ valuese were used to calculate thed values. The intensity of the peaks (linear intensity counts) isplotted versus 2θ angel (x axis in °2θ).

Single crystal X-ray diffraction data were collected at 100 K on aBruker AXS CCD Detector, using graphite-monochromated CuKα radiation(λ=1.54178 Å). The structure was solved with direct methods, refined,and expanded by using Fourier techniques with the SHELX software package(G. M. Sheldrick, SHELX-97, University of Göttingen 1997). Absorbtioncorrection was performed with SADABS software.

DSC was performed on a Mettler Toledo DSC 823e module. The sample wasplaced in crimped but vented aluminium pans. Sample size was 3 mg.
